Our invention relates to van improved vsub-vvk soil cultivator or wheeled `implement by kmeans of whichv materials in either gaseous beneath its surface f for enriching andenhancing the value of the soil forrfarming purposes. The implement embodies in its construction the well known type ofmulchf'k ing cultivator or sub-soil weeder, which is,

equipped with means for distributing the fertilizer or other materials overareas be'- neath the soil, in a thorough and rapid manner. i v y,

The invention consists in certain novel combinations and arrangements of parts for the provision of a compactlyarranged implement ofthis character, which 'is-eflicient in the performance of its yfunctions vand which may be controlled with facility.

In the accompanying.y drawingswe havev illustrated one complete example ofthe physical embodiment of our invention Whereinthe parts are combined and `arranged according to the best mode We have thus far devised for the practical application of the principles, of our invention.

Figure 1 is a plan view of a horse drawn implement embodying our invention,v Y

Figure 2 is a vertical sectional detail at line 2 2 of Figure l.

Figure 3 is a vertical sectional detail view at line-3 3 of Figure 1.'V .i Y

In carrying out our invention vwe use a horse drawn implement having a main frame 1 of rectangular shapey supported on the axle 2, and the traction wheels 3 and 3v are journaled at the ends ofthe axle in usual manner to revolve thereon. seat 4 is mounted above the main frame-for the driver, and a team of horses are attachedA or hitched to the implement at the sides of they I ting blade and distributer to the inoperative tends transversely of the implement, parallel with the axle and is located, when in operative position, .directly beneath the axle, in

such position as to penetrate and Vpass through the soil beneath its surface for mulching and cultivating the soil, as thel imn plement isk drawn along the surface of the soil. The cutting blade is suspended from .ejected out from the ings therein.v

'cureby Letters Patent is:

vBy means of a lever 9, fixed to Vthe axle,

andratchet 10 carried by the lever, and c0- 'acting with the arcuate rack plate 11 fixed' to the main frame, the'bl'ade may be swung i on the axle as a pivot to inoperative position as indicated in dotted Vlines Figs. 2 and, 3,

when not needed f or use.

At the rear ofthe transversely dis osed cutting blade 6 is carried a parallel tu ular rcasing or distributer pipe 12, fixed to thev blade by means of clamp brackets 12 and closed at one end by, means of a cap.y Per'- forations Vor openings 14' Vare arranged at the rearside of the distributer pipe and extend throughout the length of the pipe. By means of a flexible pipe or tube 15, thedistributer pipeis connected to a tanker reservoir 16 which contains gas'or liquid under pressure to be introduced through the flex. .A

pipe through the open- The material to be injected into the soilmay beQplaced under pressure within the view" tank or reservoir 16 in suitable manner, as

by the use of a pump 17 which in this in stance is operated through its crank connecible connection to the distributer pipeand tion 18 from a vpinion '19 that meshes with a'gear 20. rotatable with the traction wheel 3.' Thus as the implement is drawn over the surface of the' soil with'the cutting blade and distributer traveling below the surface, the soil is mulched by thel ybla-de and the fertilizer jorv other material is forced under'pressurev through the perforationsof the distributer and kinjected into the mulched soil. By utilizing the lever. 9 to swingthe cutdotted line positions, the implement Lmay be Adrawn' to its place of use and thepump may In a cultivat-or the combination with a main frame, supportingshaft and traction Wheels, of a transversely extending Sub-soil v cutter blade, side armev rigidly secured to the a vertioal plane, or rocked 'to adjusted pon blade and" to said supporting axle, a ratchet sition bymeans, of the lever.
